Celebes Macaque

The Celebes macaque is a frugivorous species, but immature leaves, arthropods, stalks of newly flowering plants, and cultivated crops are also consumed. Generally this species raids crops for fruits, vegetables, and maize. This is a diurnal species.

The Celebes macaque is a quadrupedal species (Fleagle, 1988).

The Celebes macaque has a multimale-multifemale social system. Females remain in their natal group with the onset of maturity, but males will disperse shortly before adolescence. There is a hierarchical system amongst group members based upon the matriline.

scream calls: This call is given by the Celebes macaque when they are approached by a non-group conspecific.


fear grimace: The lips are retracted so that the teeth are shown; the teeth are clenched together (Estes, 1991). This display functions as an appeasement signal to reduce aggression in aggressive encounters (Estes, 1991).

staring with open mouth: This is the stare accompanied by the mouth being open but the teeth are covered (Estes, 1991). This is a threat expression (Estes, 1991).

lipsmacking: This is when the lips are protruded, then smacked together repeatedly. For the Celebes macaque this display communicates aggression.


The Celebes macaque gives birth to a single offspring.
